nature of a hollow skewer on which the packages may be strung.

One object of the invention is to provide a hollow, perforated holder or skewer which is particularly adapted for mounting cops or packages of yarn or the like wound on perforated paper or liber tubes. v

Another object of the invention is to provide a hollow, perforated holder or skewer having means spaced at intervals therealong and adapted to close the ends of the tubes on which the cops or packages are wound to prevent unwarranted escape of the dye-liquor or uid at these points.

Another object of the improvementis to provide a hollow, perforated holder or skewer having bosses or hub-like enlargements at spaced intervals therealong adapted to enter the ends of the tubes on which the cops or packages are wound to substantially seal the tubes at their ends against egress oi the dye liquor or other iiuid.

Another object of the improvement is to provide annular enlargements intermediate the bosses on the holder for guiding the packagetubes to adapt them to slide freely on the holder and to aline their ends in concentric intertting relationship with the bosses.

Further objects cf the improvement `are set forth in the following specication which illustrates several preferred embodiments of the invention as illustrated by the accompanying drawings. In the drawings:

`In accordance with the modern and approved practice, yarn, thread and similar strand materials are dyed, bleached, washed and similarly treated with fluids in the form of cylindrical packages wound with What is termed a cross-wind to provide a porous mass. In certain instances the yarn or other strand material is wound on longitudinally-contractible holders to adapt the mass to be compressed to uniform density before processing; while in other cases the yarn or thread is wound on rigid cores such as paper or ber tubes havingperforations in their walls. When wound in this last-described form the packages are assembled on a hollow perforated holder, usually of tubular form, and it is necessary to employ separator plates or anges between the ends of the packages. These end-plates or disks must be placed between the ends of each two adjacent packages, which requires considerable time and effort and also necessitates their removal and replacement for subsequent dyeing operations. Besides the expense of suplying these separator plates or endc'lisks the inconvenience and labor of handling them adds to the cost of the dyeing or like operation and it is one object of the present invention-to provide means for supporting the dyecops or packages without the use of such extraneous elements. With this and other objects in View, the present invention provides a hollow, perforated holder or skewer for supporting a plurality ci packages assembled as a unit in axial alinement with means on the holder for sealing the ends of the perforated cores 0r tubes on which the yarn is Wound and further means for guiding the cores or tubes as they are strung onto the holder in series.

Referring to the accompanying drawings, Fig. l illustrates a conventional type oi dyeing vessel or kier 2 of cylindrical form having a false bottom dividing it into upper and lower compartments 4 and 5, respectively. A suitable inlet pipe 8, connected to a source of supply of dye-liquor or other fluid, communicates with the lower compartment 5 of the kier and an exhaust pipe 9 communicates with the upper compartment l to drain the fluid from the kier. In some instances the pipe 9 may be used as the supply inlet and the pipe 8 as the exhaust outlet when it is desired to reverse the direction Fig. 6 is an enlarged view illustrating a still 55 of iioW of the uid through the kier.

A cover I fitted to the top of the kier 2 is arranged to close down thereagainst with a gasket I I sealing the joint, eye-bolts I2 being employed for clamping the cover in closed position on the kier. The false bottom 3 is provided with a plurality of openings I3 for receiving threaded nipples I4 screwed thereinto and communicating therethrough with the lower compartment 5 of the kier 2.

The present improved holder or skewer is preferably constructed in the form of a standpipe I5 having perforations I6 in its Walls, and a plurality of such tubular holders may be secured in upright position on the false bottom 3 by providing them with eXteriorly-threaded ends I1 (see Fig. 2) screwed into the interiorly-threaded upper portions of the nipples' I4. The upper ends of the standpipes -or holders I5 are closed by Stoppers in the form of plugs I8 having eX- ternal screw-threads at their outer ends for receiving collars or nuts I9. The nuts I9may be in the form of interiorly-threaded hubs having radially-'projecting prongs or lingers 20 to provide for convenience in turning them by hand, the hubs or nuts I9 being adapted to be screwed down onto the ends of the holders I5 to abut the ends of the cop-tubes or cores of the endmost packages in the series mounted on the holders.

Referring now particularly to Figs. 2 and 3, the present improved skewer or holderV I5 is provided with a series of bosses or enlargements 25 spaced at regular intervals therealong in conformity with the length of the package-cores `or cop-tubes used with the holder. Usually, each holder or standpipe I5 is of suflicient length to; support five or more cylindrical packages of yarn of `approximately six inches in length and with the arrangement shown in Fig. 1 four bosses 25 are provided on the holder adapted to register with the ends of the tubes for the five packages. The upper and lower ends of the standp-ipe or holder I5 are also provided with eri--I largements or bosses 26 and 21 which may be of yless length than the intermediate zones. The bosses 25, 26 and 21 may be made integral with the tubular holder or standpipe l5 or they may be formed separate therefrom and shrunk onto the pipe.

The packages of yarn or the like, designated P and represented by dash lines in Figs. 2 and 3, are usually of cylindrical form with the strand material wound on tubes t of paper, fiber or similar light material, the tubes being of slightly greater length than that of the packages and perforated substantially throughout their extent with relatively small holes or apertures h. A plurality of packages P are assembled on the holder I5 by sliding their tubes t therealong to position them with their ends'abutting, the spacing and dimensions of the bosses 25 being such as to provide a substantial length of each boss projecting into the end of each tube. Likewise, the ends of the tubes t of the top and bottom packages are supported on and stoppered by the bosses 26 and 21. 1

As another feature of the present invention the holder or standpipe I5 is provided with further enlargements or. annular projections 30 arranged equidistantly between the larger bosses. That is to say, one of these annular enlargements 30 is spaced equidistantly between the bosses 26 and 25 at the top of the holder I5 and between the bosses 25 of each pairprogressing downwardly, with the last annulus 30 spaced equidistantly between the last boss 25 and the bottom boss 21. These annular enlargements 30 serve an important function for engaging the the holders or standpipes.

interior of the cop-tubes t as they are slid downwardly on the standpipe I5 to guide them over andv onto the longer bosses 25. Preferably, the several bosses and annuli are beveled or rounded olf at their ends to provide for their easy entrance into the ends of the cop-tubes t. Without these intermediate annular enlargements or guiding bosses 30 it would be practically impossible to slide the cop-tubes t onto or oii from The intermediate bosses or annuli 30 maintain the cop-tubes t concentric with the periphery of the tubular holders I5 and thus guide the ends of the tubes from one boss to another, it being noted by reference to Fig. 4 that when a tube is slid over one of the larger bosses its end will engage around an in.

termediate boss before its upper end is freed from the larger boss. Thus the cop-tubes t are continuously maintained in concentric relation to the bosses so that the packages may be readily and conveniently placed on the holder I5 by sliding the tubes while they are guided by the intermediate bosses or annuli 30 to pass from one boss to another until all the packages are assembled in position as shown in Fig. 2 with the ends of the cop-tubes t supported on and stoppered by the longer bosses 25, 26 and 21.

While it has been found sufficient for the purpose intended to provide one intermediate boss or annulus 3U between each two larger bosses 25, if desired a plurality of such intermediate bosses may be formed on or applied to the holder I5 as shown in Fig. 5. In this modied form of construction of the device three projecting rings or narrow bosses 35 are provided between each two larger bosses 25, being equidistantly spaced in relation to each other.

In the modified form of construction shown in Figs. 6 and 7 the narrow guiding boss 31 is shown v as slotted or fluted on its periphery to provide passages for the fluid so as not to obstruct its flow through the interior of the cop-tube t.

The present improved package-holder or skewer having been described in detail its method of operation in connection with its use in a dyeing vessel or kier isy explained as follows:

The present improved package-holder or standpipe I5 is used in multiple in the kier 2 and may be permanently attached to the false bottom 3 thereof; or, if desired, each holder may be removable from the kier to provide for assembling the packages thereon before they are placed in the kier. In either instance the packages P may be readily and conveniently placed on the holder I5 by sliding their cores or tubes t downwardly thereon while the holder is arranged in upright position. Each package P is applied to the holder I5 by slipping its tube t over the end boss or enlargement 26 and sliding it downwardly thereon, whereafter the interior of the tube will be engaged by the guiding boss or annulus 3D. 'Ihe tube t is thus maintained concentric with the periphery of the holder I5 to aline its end with the next larger boss 25 to adapt it to slide freely thereover. The first package P placed on the holder in this manner is slid the entire length of the standpipe until the end of its tube t engages around the last boss 21 and brings up against the flange on the nipple I4. The whole series of packages P, usually five or more in number, are applied to the holder I5 in the manner explained above and finally the hub 1 or nut I9 is screwed onto the threaded end of the plug I8 to bring the ends of all the cop-tubes t into abutting relationship and maintain the packages in place on the holder.

After a batch of yarn-packages P have been applied to the several holders I used in the kier 2, the latter being grouped to substantially fill the interior of the kier with yarn, the cover IB is placed on top of the kier and fastened tightly in place by means of the eye-bolts i2. With the apparatus thus prepared' for a dyeing or similar operation the dye-liquor or other uid is pumped into the lower compartment 5 by way of the inlet pipe 8 to cause it to be forced upwardly through the hollow holders or standpipes I5, whence it escapes through the perforations IE in the walls of the standpipes and through the perforations h in the cop-tubes t to permeate the yarn masses surrounding the latter. The dye-liquor or other fluid is exhausted from the upper chamber 4 of the kier through the pipe 9 and usually pressure is maintained in the lower compartment 5 with a partial vacuum in the upper chamber li. If desired, the iiow of the dye-liquor may be reversed by forcing it through the pipe 9 into the upper chamber il and exhausting it down through the bottom chamber 5 and out through the pipe 8. In some instances both systems are employed with the dye-liquor or other fluid forced through the yarn mass in the packages from the inside outwardly, and then from the outside into the interior thereof.

It will be noted by reference to Fig. 2 of the drawings that when the packages P are assembled on the standpipe or holder I5 their cop-tubes t are supported with their walls spaced outwardly from the sides of the standpipe, except at the points where the ends of the tubes surround the bosses 25, 26, 21 and 3g. ment annular chambers are provided between the outer periphery of the standpipe l5 and the inner walls of the tubes t so that the fluid emerg' ing from the holes l5 in the standpipe under pressure will fiow along these chambers to find' egress at the holes h in the cop-tubes t. For this reason the holes or perforations h in the oop-tubes t need not be alined with the holes iii in the standpipe l5 to maintain a steady and uniform iiow of the fluid through the packages.

In the modified form of construction illustrated in Fig. 6 of the present drawings the guiding boss or annulus 3'! is shown as being liuted on its periphery so that it will not obstruct the flow of the fiuid along the interior of the cop-tube t, although this is not essential to the proper functioning of the device. In any case, there are usually a suiicient number of holes I6 between Through this arrangethe bosses to supply a plenitude of fluid to the interior of the cop-tubes t and thence through their perforations to the wound masses of yarn thereon.

It will be observed from the foregoing that the present invention provides a simple and ingenious construction of package-holder or skewer for mounting series of textile oops or packages in condition for dyeing or other huid-treatment processes. By providing means on the holder for stoppering or closing the ends of the cop-tubes the iiuid is prevented from free escape at the ends of the packages, while at the same time longitudinal passages are formed within the interior of the cop-tubes for the unrestricted flow of the uid through the apertures in their walls. As a further feature of improvement, the provision of guiding bosses or annuli between the larger bosses for supporting the tubes at pointsv spaced therealong serves to maintain the tubes always in concentric relation to the exterior of the holder as they are slid into place thereon so that they are not obstructed as they slide 01T from one bos and onto another.

While the invention is herein described and illustrated in its preferred form with several modifications shown, it is to be understood that other changes may be made in the form and construction of the apparatus without departing from the spirit or scope of the invention. Therefore, without limiting ourselves in this respect, we claim:

l. A holder or skewer for supporting a series of dye-cops or packages of yarn and the like consisting in a tubular member having perforations in its walls, rigid and imperforate annular enlargements on the periphery of said tubular member spaced at intervals therealong in position to engage and seal the interior of the ends of the cop-tubes or cores of the packages strung on the holder, and guiding bosses of less aXial length than the first-named bosses arranged between the latter.

2. A holder or Stringer for supporting a plurality of dye-cops or packages of yarn or the like comprising a tubular member having perforations in its walls, rigid and imperforate annular bosses spaced along its length to adapt them to enter and close the ends of the cop-tubes in the packages strung on the holder, and guiding bosses arranged between the rst-named bosses and fluted on their peripheries to provide for free passage of the dye-liquor or other fluid between the first-named bosses.
